Toxic Algae Blooms Occurring More Often, May Be Caught in Climate Change Feedback Loop

This article discusses the impact that climate change is having on algae and GHGs.

The blooms, primarily fed by farm runoff but exacerbated by warming, release methane and CO2. Lake Erie is a ‘poster child’ for the challenge.

Blooms of harmful algae in the nation’s waters appear to be occurring much more frequently than in the past, increasing suspicions that the warming climate may be exacerbating the problem.

The Environmental Working Group (EWG) published newly collected data on Tuesday reporting nearly 300 large blooms since 2010. Last year alone, 169 were reported. While NOAA issues forecasts for harmful algal blooms in certain areas, the advocacy group called its report the first attempt to track the blooms on a nationwide scale.

The study comes as scientists have predicted proliferation of these blooms as the climate changes, and amid increasing attention by the news media and local politicians to the worst cases.
